Like Larry I am a bit dubious of some signed covers.
Since my original post about Arnold Machin signed covers and Larrys reply there seems to be quite a lot appearing on the market. As well as the one described yesterday I spotted another last week, so these although nice objects are not as rare as I fist thought.
I have also come across this one left (ending 1st September) unlike the one which I reported on yesterday which has a start price £27.50.
This one has a low start price of £7.99. It is double signed.
It looks to be a cover with the first 3 pre decimal stamps issued in 1967 and a gold 1st class stamp dated 1997 (5th June) for the 30th Anniversary Machin stamps.
Described as a Benham cover signed by Arnold Machin (1911-99) & Lord Glenamara (Edward Short), who was Postmaster General in 1967.
